Subject: [PATCH v2 3/3] riscv: dts: spacemit: enable USB3 on OrangePi RV2
Date: Thu, 2 Apr 2026 18:00:07 +0800 [thread overview]
Message-ID: <20260402100007.110201-4-amadeus@jmu.edu.cn> (raw)
In-Reply-To: <20260402100007.110201-1-amadeus@jmu.edu.cn>
Enable the DWC3 USB3.0 controller and its associated PHY on
the OrangePi RV2. The onboard GENESYS GL3523 Hub provides 3
USB3 Type-A ports. Enable the corresponding VBUS regulator.
